The Comprehensive Evaluation of Rural Drinking Water Security in Yunnan Province

In view of the uncertainty and ambiguity of the rural drinking water security, the paper built the fuzzy matter-element model based on the entropy weight, combining entropy theory with fuzzy matter-element. And on that basis, in Yunnan province, for instance, the rating system was constructed with six indexes such as the proportion of people without guarantee of water and per capita water consumption; the results show that the state of rural drinking water security overall on low level in Yunnan provides the evidence of constructing rural drinking water security safeguard measure.
